We divide 64580645 by 339
Our goal is to divide 64580645 by 339.

Going ahead to step 1:
If we divide 6 by 339, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 339

Going ahead to step 2:
The number 339 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 339

Going ahead to step 3:
339 goes into 645 1 times with a remainder of 306.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 339 from 645 and we're left with 306.
Grab the next digit (8) from the dividend, add it to 306, then carry on: 3068 / 339

Moving on to step 4:
When dividing 3068 by 339, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 3051 from 3068 to get 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 339

Step 5:
If we divide 170 by 339, we get 0 and a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 190.0
Deduct 0 from 170 and we're left with 170.
Append the next digit (6) from the dividend to 170 and continue with: 1706 / 339

Going ahead to step 6:
If we divide 1706 by 339, we get 5 and a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 1905.0
If we take 1695 away from 1706, we end up with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 339

Advancing to step 7:
339 goes into 114 0 times with a remainder of 114.
Record the quotient 0 as the next digit in the result. 
Result so far: 19050.0
Subtract 0 from 114 to get 114.
Grab the next digit (5) from the dividend, add it to 114, then carry on: 1145 / 339

Step 8:
1145 divided by 339 is 3 with a remainder of 128.
Record the quotient 3 as the next digit in the result. 
Result so far: 190503.0
Subtracting 1017 from 1145 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 9:
339 can be fit into 1280 3 times, resulting in a remainder of 263.
Record the quotient 3 as the next digit in the result. 
Result so far: 190503.3
If we subtract 1017 from 1280, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 10:
The number 339 fits into 2630 7 times, leaving a remainder of 257.
The next digit of our result is 7. 
Result so far: 190503.37
Subtracting 2373 from 2630 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Going ahead to step 11:
339 goes into 2570 7 times with a remainder of 197.
Write down 7 as next digit of the result. 
Result so far: 190503.377
Subtracting 2373 from 2570 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

After the division, we end up with 190503.377 and a remainder of 0.0197.
